[Clinical practice for the diagnosis of cardiac arrhythmias in patients on renal replacement therapy: data from a Lombard survey].

Among dialysis patients, 40% of deaths are due to cardiovascular causes, and 60% of cardiac deaths are due to an arrhythmia. The purpose of this survey, carried out with the organizational support of the Lombard Section of the Italian Society of Nephrology, is to evaluate the frequency and mode of use of non-invasive instruments for the diagnosis of cardiac arrhythmias in the dialysis centers of Lombardy. Information on the prevalence and type of cardiac devices at December 1, 2016 in this population was also required.

The peritoneal sieving of sodium: a simple and powerful test to rule out the onset of encapsulating peritoneal sclerosis in patients undergoing peritoneal dialysis.

Background And Aims: Encapsulating peritoneal sclerosis (EPS) is an uncommon but severe complication of peritoneal dialysis (PD). A reliable screening tool to identify patients at risk of developing or not EPS is currently not available. We aimed to evaluate whether the reduction in dialysate sodium concentration (sodium sieving) at 60 min (ΔD), during a peritoneal equilibration test with 3.

Frequency and targeted detection of HLA-DPB1 T cell epitope disparities relevant in unrelated hematopoietic stem cell transplantation.

The majority of unrelated donor (UD) hematopoietic stem cell (HSC) transplants are performed across HLA-DP mismatches, which, if involving disparity in a host-versus-graft (HVG) direction for an alloreactive T cell epitope (TCE), have been shown by our group to be associated with poor clinical outcome in 2 cohorts of patients transplanted for hematopoietic malignancies and beta-thalassemia, respectively. Using site-directed mutagenesis of DPB1*0901, we show here that the TCE is abrogated by the presence of amino acids LFQG in positions 8-11 of the DP beta-chain. Based on this and on alloreactive T cell responsiveness, we have determined the presence or absence of the TCE for 72 DPB1 alleles reported in the ethnic groups representative of the worldwide UD registries, and predict that 67%-87% (mean 77%) of UD recipient pairs will not present a DPB1 TCE disparity in the HVG direction.
